Letâs face it: Most of us don't give much thought to our pee before we flush it out of sight. But the basic details of your urine -- color, smell, and how often you go -- can give you a hint about whatâs going on inside your body. Pee is your bodyâs liquid waste, mainly made of water, salt, and chemicals called urea and uric acid. Your kidneys make it when they filter toxins and other bad stuff from your blood.
Further refining may be performed using one of two processes. In cementation, the acidic solution of copper is deposited on to scrap iron in an oxidation-reduction reaction. After sufficient amounts of copper have been plated, the copper is further refined using the pyrometallurgical process.
Recycling scrap metal reduces greenhouse gas emissions and uses less energy than making metal from virgin ore. The amount of energy saved using various recycled metals compared to virgin ore is up to: Metal Recycling Conserves Natural Resources. Metal recycling also conserves natural resources.Recycling one ton of steel conserves 2,500 pounds of iron ore, 1,400 pounds of coal and 120 pounds of limestone.Recyling a ton of aluminum conserves up to 8 tons of bauxite ore and 14 megawatt hours of electricity.etal recycling also conserves natural resources.
